java - Could not instantiate collection persister with JPA -
now development 1 multi-tenant system, use spring-boot jpa , hibernate.
there problem when want persister 1 collection. @ code, there have 1 embeddable class 'account', , @ tenant class, have 1 set<account>
tenant
@entity @table(name = "tenant", uniqueconstraints = @uniqueconstraint(columnnames = "tenant_id")) public class tenant extends concurrentsafeentity<tenant, tenantid> { private static final long serialversionuid = 6910165036330125453l; @embeddedid private tenantid tenantid; @column(length = 20, nullable = false) private string name; @elementcollection @collectiontable(name = "tenant_account") private set<account> accounts; ... } account
@embeddable public class account implements valueobject<account> { private static final long serialversionuid = -2780296854441642870l; @embedded private accountnumber accountnumber; @embedded private encryptedpassword password; ... } accountnumber
@embeddable public class accountnumber implements valueobject<accountnumber> { private static final long serialversionuid = -2737145407283086518l; @column(name = "account_number", nullable = false, updatable = false) private string source; @column(name = "type", nullable = false, updatable = false) private string type; ... } but when test by
@test public void constructor() throws exception { tenant tenant = new tenant( tenantrepository.nextidentity(), "aname", new accountnumber("test@wcscent.com", "email"), new encryptedpassword("apassword", encryptionservice), validator ); tenantrepository.save(tenant); } error is

thanks!
ok, resolve problem track hibernate code. , because codes don't standard pojo.
it means properties of classes may don't have getter or setter. hibernate cannot find them.
but think may bug. because situation happened @ accountnumber , encryptedpassword. , belong account.
in other words, if properties belong tenant or account, hibernate can find them, if them don't have getter , setter. if properties belong accountnumber , encryptedpassword, hibernate wouldn't find them when them don't have getter , setter.
